The "Donald Duck song" (also known as "No One But Donald Duck") was the theme song for Donald Duck's cartoons from 1947 (Donald's Dilemma) to 1959 (How to Have an Accident at Work). Today, it stands as his official theme song. None of the lyrics (except for the second-to-last verse) describe him accurately.
Who's got the sweetest disposition?
One guess--guess who!
Who never never starts an argument? (Woman: Hmmmm?)
Who never shows a bit of temperament?
Who's never wrong but always right? (Donald: Yeah?)
Who'd never dream of starting a fight? (Donald: That so?!)
Who gets stuck with all the bad luck?
No one...(Donald quacks angrily) but Donald Duck! (Donald: Yeah!)
